IIRC we already agreed off-list regarding USB enclosures and the
firmware a while ago.

I can not remember that we discussed wiring issues.

IMO it's super-very-most-unlikely a wiring issue. I can't imagine a
reasonable wiring issue.

What the OP describes is the common (I like your wording) "works here,
but not there" and "works sometimes, but not always" firmware issue.

In the beginning I disassembled the drives and connected them to my PC
to test, if the drives are broken. Nowadays I don't even test the
drives, I directly return such USB enclosures. I even don't waste time
to test another USB port ;), let alone another computer.
